> WildcardPermission case-insensitive makes parts collections twice
> -----------------------------------------------------------------
>
> Key: SHIRO-564
> URL: https://issues.apache.org/jira/browse/SHIRO-564
> Project: Shiro
> Issue Type: Improvement
> Components: Authorization (access control)
> Affects Versions: 1.2.4
> Environment: Any
> Reporter: Matt Bishop
> Priority: Trivial
>
> WildcardPermissions have a caseSensitive flag that instructs the permission
> to ignore case when comparing permissions. It's implementation of this
> feature is kinda wasteful because it first parses the permission string into
> a Set<String> part, THEN checks the flag and then rebuilds the part Set.
> It might be faster to check the flag first, lowercase the permission string,
> then parse the parts. This would save creating a whole bunch of extra
> LinkedHashSets.
